Many tests were
run on black coroplast panels to establish the water heating
efficiency for a swimming pool. The main objective was to
calculate the maximum power produced by a single black
coroplast panel of 4 feet by 8 feet by monitoring the
changes in temperatures between the inlet and the outlet
while the system was running.

Solar panel used for the test

We monitored the water temperature between the inlet (T1)
and the water outlet (T2) using a high precision thermomiter.
Water
flow was also carefully monitored during the tests. Using
an equation, we easily found the power developed by the
panel in Watts or BTU.

Results were astonishing. The tested solar panel has
reached up to 3500 watts (11943 BTU/h).

In fact, we could say that this single coroplast panel of 4
feet by 8 feet has heated the pool water as if we had used a
3500 watts electrical element, the equivalent of
conventional water tank heater or 35 electric bulbs of 100
watts each!

Your solar
water heater will be made of several of theses panels
jointed together supplying a very powerful heating
capacity.

A second series
of tests consisted in linking 4 solar panels to a pool 24
feet round in diameter and to determine the elevation of
temperature. The 4 solar panels used were constructed by
following precisely the instructions of the video (DVD).

The result was
again surprising. Indeed, the 4 solar panels have produced
up to 14,000 Watts (14 kilo watts) of heat energy when the
sun was at its strongest.

We therefore
compared the water temperature of 2 identical 24-foot
diameter pools. One was equipped with no heating while the
other was equipped with 4 coroplast panels. After a day, the
temperature of the pool with 4 solar panels was above 10
degrees Fahrenheit!

As you can see,
it is possible to get very high water heating power by
joining together many solar panels between them. Imagine
the speed at which your swimming pool could heat up!

Our DVD will
clearly explain you, step by step, how to build your own
solar panels to be as weather resistant and efficient as
possible. By assembling these panels as shown on the DVD,
you will avoid many frustrations and problems.
